英文摘要In this paper, the first moments of the peaks eluted from a two-dimensional packed-capillary column GC system were derivde by means of chromatographic dynamics, Based on this expression, the effect of the precolumn temperature, the precolumn pressure and the split ratio on the retention time and the peak spreading were discussed, The results showed that split stream was a bridge between the main column and the precolumn, the split ratio was an important factor affecting the retention time and the peak spreading, Because the retention period of the solute in precolumn was shorter, the effect of the change of the precolumn condition on retention time was smaller if the main column condition was,fixed, The higher the temperature of precolumn and the more narrow the peak, and the pead profile could be improved in a regular scope by the change of the split ratio between the two column. In accordance with the relationship between the main column and precolumn, some special rules were observed in the two-dimensional packed-capillary column GC system.
